Answer:

2π

Step-by-step explanation:

When a circle's radius is 1—called a unit circle—its circumference is 2π.

Answer:

h + c = 3 and 4h + 4c =10

No solutions

Step-by-step explanation:

If hot dogs = h, and chips = c,

Then the first scenerio can be written as h + c = 3

The second scenerio is 4h + 4c = 10.

So, your system should be

h + c = 3 and 4h + 4c =10

Solve this system

First, solve c + h = 3 for c.

Subtract h on both sides.

c = -h + 3

Then, substitute c = -h + 3 into the second equation (4c + 4h = 10)

4(-h + 3) + 4h = 10

Simplify.

- 4h + 12 + 4h = 10

12 = 10

This is not right, so this system has no solutions. This means that there is no set cost for the chips or hot dogs (or for both).

Hope this helps! Feel free to ask any questions

Step-by-step explanation:

years of equal population are 1995 and 2022.

in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.

Step-by-step explanation: Baskinville: y = x2 - 22x + 350

Cryersport: y = 55x - 950

Note that x2 is xsquare not x2

Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

Answer:

6

Step-by-step explanation:

first let's find all the possible combinations excluding 6+6 to get 12 using addition, we exclude 6+6 because we can't have the same integer for different variables. these are 0+12, 1+11, 2+10, 3+9, 4+8, and 5+7(also the other way around but i start with these). using common sense, I started higher because there is no way d = 0 and e= 12, so i went from 5+7 down. through trial and error and some luck, 5+7 was the correct combination. let's insert the numbers with their variables. d = 5 and e = 7. now we figure out, what minus 5 is 7? if you learned fact families in kindergarten, you'd know to find this out you add 5+7, which is 12. now we divide 12 by 2, because it's the same number added together to get this number, so you now get 6+6. does the equation make sense? (6+6) - 5 = 7, that checks out, and 5+7=12.

Answer:96.34%

Solution for 79 is what percent of 82:

79: 82*100 =

(79*100): 82 =

7900: 82 = 96.34%

Answer:

64.72

79 percent *82 =

(79:100)*82 =

(79*82):100 =

6478:100 = 64.78

Now we have: 79 percent of 82 = 64.78

Step-by-step explanation:

15 divided by 5 equals 3

Answer:

170

Step-by-step explanation:

1. change 15% to decimal - 0.15

2. multiply it by the regular price ($200) - 0.15 x 200 = 30

3. subtract the regular price by the discounted price - 200 - 30 = 170

Answer:

[tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

[tex]\frac{9*5}{4*3}[/tex]

[tex]\frac{45}{12}[/tex]

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

[tex]3\frac{3}{4}[/tex]

Simplify given fraction into mixed fraction is 3³/₄

Give that:

[tex]2\frac{1}{4} \times 1\frac{2}{3}[/tex]

Find:
